Total questions: 10
Worksheet time: 6mins
What are the two parts of oxidative phosphorylation?
glycolysis
Krebs cycle
electron transport chain
chemiosmosis
Where does oxidative phosphorylation take place?
chloroplast
cristae
matrix
cytosol
Which direction are protons pumped during the electron transport chain?
Into the mitochondrial matrix
Into the intermembrane space
Into the cytosol
Into the thylakoid
Which part of the cell will have the highest pH due to cellular respiration?
cytosol
matrix
intermembrane space
thylakoid
How does the electron transport chain facilitate the synthesis of ATP?
The ATP is synthesized at the end of the electron transport chain
The ATP is synthesized by the protons combining with the oxygen in the electron transport chain
The ATP is synthesized by the protons flowing down their concentration gradient after being pumped out by ETC
The ATP is synthesized by the ATP synthase found in the electron transport chain
What is the function of decoupling oxidative phosphorylation in the electron transport chain?
Generate heat to regulate body temperature in endotherms
Generate heat to regulate body temperature in ectotherms
Generate ATP to power cellular activity in cells
Generate ATP to power activity in organisms
What does the NADH and/or FADH2 that is brought to the electron transport chain come from?
Glycolysis
Krebs cycle
Pyruvate oxidation
Cytoplasmic reactions
Where would you find the electron transport chain in a plant cell?
mitochondrial cristae
thylakoid membrane
prokaryotic plasma membrane
endoplasmic reticulum
Golgi bodies
Describe what would happen if the mitochondrial inner membrane was ruptured.
ATP synthesis would be inhibited
ATP synthesis would be promoted
The electron transport chain would increase in activity
The electron transport chain would decrease in activity
FUN FACT: How many ATPs are synthesized from the energy carried by NADH and FADH2 (on average)?
1 NADH = 1 ATP; 1 FADH2 = 1 ATP
1 NADH = 2 ATP; 1 FADH2 = 1 ATP
1 NADH = 3 ATP; 1 FADH2 = 2 ATP
1 NADH = 2 ATP; 1 FADH2 = 3 ATP
